Based on coordinate transformation incorporated with conformal mapping approach, a sub-wavelength imaging device with magnification, called "planar hyperlens" is designed, capable of realizing far-field plane-to-plane imaging beyond the diffraction limit. The possible implementation method is proposed by using effective anisotropic metamaterial formed by alternating metallic and dielectric thin layers. The magnification performance of the designed multi-layer lensing structure is numerically simulated to confirm our theoretical analysis.
基于结合共形映射方法的坐标变换，设计了一种具有放大功能的亚波长成像装置，称为“平面超透镜”，它能够实现超越衍射极限的远场平面到平面成像。提出了利用由交替的金属和电介质薄层形成的有效各向异性超材料的可能实现方法。对所设计的多层透镜结构的放大性能进行了数值模拟，以证实我们的理论分析。
